IPC: H01F27/28
Filed: 1984-12-25
Abstract: PURPOSE:To prevent the decrease of electric field intensity without making work process complicated, by alternatively arranging the connecting parts of the liquid accumulators of each cooling duct installed in parallel to the built direction of winding and the insulating pipes as the neighboring liquid accumulators are connected to each insulating pipe at their opposite ends. CONSTITUTION:The liquid accumulators 31a-31c arranged in the built direction of winding 33 are connected to the insulating pipes 12 as the neighboring accumulators have inverse direction with each other. The cap nut 23 at the top of liquid accumulator and the hollow bolt 24 at the top of insulating pipe 12 are tightened and fixed with each other. The connection part of them is covered by a dome-shaped shield material 34. As the connecting parts of the liquid collectors 31a-31c and the insulating pipes 12 are inverse with each other with respect of the neighboring liquid accumulator, the distance for insulation between then can be sufficiently obtained, and dielectric strength is increased. As it is unnecessary to manufacture the bolt and nut into round shape, the extra work process can be dispensed with.

Abstract: PURPOSE:To adjust the operating range of a reception part matching with the level of a transmission wave used in a transmission system by setting the levels of all the input signals less than a receivable level by inserting a limiter on the four-line side output of a hybrid transformer. CONSTITUTION:Diodes 10 and 11 for amplitude control are inserted to the four-line side output of the hybrid transformer 16 in data transmission equipment 1 provided with the hybrid transformer 16 whose two-line side output is connected to a digital communication line, a transmission part 13 connected to the four-line side output of the hybrid transformer 10, and a reception part 12 connected to the four-line side output of the hybrid transformer 16. Since the reception part 12 requires capacity for the reception of an input signal with a wide range from the level of a transmission signal to a micro level attenuated on the middle way of the line, no guarantee of operation is given on the input signal with the level over that of the transmission signal so as to extend the range of a reception level to a low level area side. The diodes 10 and 11 for amplitude control apply the function of a limiter on the input signal with reception capacity exceeding over that of the reception part 12.

Abstract: PURPOSE:To prevent the erroneous actuation of a transmission control circuit by providing a power source control circuit between the transmission control circuit and a connection cutoff means and always supplying the electric power of a power source to the transmission control circuit in case of setting the connection cutoff means on a connection side. CONSTITUTION:At the time of an instantaneous interruption of service which occurs in a trunk switching in a central telephone exchange or at the time of occurring an instantaneous power failure which occurs in the inversion at the time of incoming call, the power source control circuit 67 supplies a current to a terminal B2 of the base of an NPN type transistor Tr2 by the discharge of a capacitor 69. And since the collector emitter of the NPN type transistor Tr2 is connected and also the base of a PNP type transistor Tr1 is connected, the emitter collector of the PNP type transistor Tr1 is connected. Therefore, since a switch 66a is closed, a no-voltage state does not occur in the transmission control circuit in the midst of the control of transmission and the charging current of a power source circuit 8 is always supplied to the transmission control circuit, so that the control of transmission in a terminal device can be accurately executed.
